Google is a commercial enterprise... 'nuff sed.
To elaborate...Google is an advertising and marketing company!! Everything they do, is directed towards knowing the consumer. This EULA is genius...and so is this product (the browser). What better way is there of harvesting consumer information? Create a browser, say you have royalty-free license to everything that goes through said browser. This is a like striking gold for an advertising company. It is essentially spyware, only made by Google so it's good...right?
